I had a friend who had bad luck with his wife in McCall Idaho and took his 10X12X5 wall tent up to 6,000 feet just out of town and spent 2 years in it on State ground.He used the old original type sheepherders stove they used in there wagons and stayed quite warm in below zero temps and several feet of snow.

His secret was a plastic barrier around the whole tent like a buffer.He dried his fish and meat from wires above the stove and buried them.I snowmobiled into his camp once and was quite impressed with his set-up and the warmth but it stunk from the drying meat. grin

I have a 10X12X5 my wife got me for our anniversary and I also used the old style herders stove but have changed to a barrel type stove out of a 30 gallon barrel.I love the wall tents and have spent many months in them before I could afford a camper..My first one was a 8X10 that did the trick working but was small and I sold that to Ray Arnold the back country mail man he put in his airplane for emergency's.
